People are taking you awfully literally here. I think the idea of only having to ever configure and trust 1 device is fantastic.

I guess people are thinking of the integration that is available today and how awkward it is, rather than the integration that can happen when everything ships with support for working with everything else.

Sure the software needed at the center of it doesn't exist, but there isn't any fundamental limitation on presenting device appropriate interfaces, it's just integration work.
